filterlog

filterlog(8)						      System Manager's Manual						      filterlog(8)

NAME

       filterlog - Logs and reports system Correctable Read Data (CRD) memory errors on specific systems.

SYNOPSIS

       /usr/sbin/filterlog [-l] [-d crdlog] [-d crdlifetime] [-s crdlength #] [-s crdcount #] [-h]

OPTIONS

       Logs  or  filters an entry from stdin. This option is used by the binary event-log daemon, binlogd.  Dumps the contents of the CRD log file
       in text format.	Errors shown in the file are those recorded by the system since the last boot.	Dumps the CRD lifetime log information	in
       text  format.   Used to set the CRD interval time in minutes. The default is 24 hours.  Used to set the CRD interval count.  The default is
       50.  Prints a list of the command option options defined in this reference page.

DESCRIPTION

       This utility ensures that only genuine memory errors are reported to system log files on certain system types.  The  command  filterlog	is
       called  directly  by the binary event-log daemon, binlogd to filter system CRD (memory hardware) errors. CRD errors are logged according to
       user-definable parameters.  If it is determined that a genuine memory problem exists, an entry is passed to binlogd.  The error	will  then
       be written to the system's error log file and can be notified to the user through DECevent.

       The filterlog utility uses two variables to determine if a CRD error signifies a genuine memory hardware problem -- crdlength and crdcount.
       If crdcount number of errors occur during crdlength minutes, an entry is passed to binlogd.  The default settings are 50 errors in 24 hours
       (1440 minutes).

       The filterlog utility reads the /etc/binlog.conf file to determine what log file should be used to record any events.  The default log file
       is /usr/adm/binary.crdlog.
